基于GPS的打铃器设计之软件部分

Software design of Ling device based on GPS

介绍了一种以AT89C51单片机、DS1302时钟芯片和GPS接收器为核心的新型打铃器。分析了打铃器的硬件系统构成、工作原理,并对软件的编程过程进行了详细的阐述。打铃器以DS1302为基准时间、走时精确、万年历时间显示、大约可存储50条作息时间,掉电数据不丢失。在软件的编程中,软件采用子程序模块化结构设计,使程序功能强,调试效率高;经在多所学校测试,均实现了定时、存储和控制功能,具有很高的科研和商业价值。

A new bell device made up with the core chip AT89C51, DS1302 clock chip and the GPS receiver is introduced. The composition of hardware, work principle and programming flow of part software are presented in detail. Bell device with DS1302 as the reference time, accurate, calendar time display, some can store 50 hours, and data is not lost without electricity. During programming, the software is designed as the modular subroutine structure, so that it has the strong feature and can debug efficiently. After testing in many schools, it has been proved to achieve the timing, storage and control functions, with a high scientific research and business value.
